CSV to JSON Converter

CSV to JSON Converter reads comma-separated data — the format every spreadsheet exports — and turns it into a tidy JSON array of objects, using the first row as the keys. It correctly handles quoted fields that contain commas and line breaks.

Everything is parsed locally in your browser, so your data is never uploaded.

How to use CSV to JSON Converter

  1. 1

    Paste your CSV

    Include a header row; each following row becomes one JSON object.

  2. 2

    Convert

    Click Convert to JSON to produce a pretty-printed array of objects.

  3. 3

    Copy the JSON

    Copy the output into your code, API request or configuration file.

How the CSV is parsed

The first line is treated as the header and supplies the property names for every object. Each subsequent line becomes one object, matching values to columns by position.

The parser follows the common CSV rules: fields may be wrapped in double quotes, a doubled quote inside a quoted field represents a literal quote, and quoted fields may contain commas and newlines without breaking the structure.

From Excel to JSON

Spreadsheet programs like Excel and Google Sheets can export any sheet as CSV. Save your sheet as CSV, paste it here, and you have JSON ready for an application or API — no scripting required.

All values are imported as strings, which keeps the conversion predictable. Cast numbers or booleans in your own code if your application needs typed values.

Frequently asked questions

Does it handle commas inside quoted fields?
Yes. Fields wrapped in double quotes may contain commas, line breaks and escaped quotes, all parsed correctly.
Are values converted to numbers?
No. Every value is kept as a string for predictability. Convert types in your own code if needed.
What does it use for keys?
The first row of the CSV is used as the property names for every generated object.
